autowisp.browser_interface.processing.select_photref_views module
Class Inheritance Diagram
Implement the view for selecting single photometric reference.
- autowisp.browser_interface.processing.select_photref_views._create_merit_histograms(merit_data, image_index, max_photref_separation=0.2)[source]
Create SVG histograms of various merit metrics showing image in each.
- autowisp.browser_interface.processing.select_photref_views._create_pointing_plots(merit_data, image_index, max_photref_separation=0.2, zoom_threshold=3, **plot_cfg)[source]
Create SVG plots for pointing: RA vs Dec scatter and separation histogram.
Images within max_photref_separation * diagonal_fov of the current image are drawn with in_range_cfg, those outside with out_of_range_cfg, and the current image itself with this_img_cfg. RA axis is inverted per astronomical convention. The separation histogram includes a vertical line at the threshold.
If the maximum separation among all images exceeds zoom_threshold * threshold_deg, an additional zoomed scatter plot is appended that restricts the view to images within that radius so the in-range clustering remains visible despite the wider spread. Images in the zoomed plot are still coloured by the original threshold_deg.
- Returns:
List of SVG strings, or empty list if the required diagnostics (ra_center, dec_center, diagonal_fov) are absent.
- autowisp.browser_interface.processing.select_photref_views._get_merit_data(request, target_index)[source]
Add to the session the merit information for selecting single ref.
- autowisp.browser_interface.processing.select_photref_views._get_missing_photref(request)[source]
Add all frame sets missing photometric reference to the session.
- autowisp.browser_interface.processing.select_photref_views.create_svg(fig)[source]
Save fig to an SVG string, close the figure, and return the string.
- autowisp.browser_interface.processing.select_photref_views.get_photref_merit_info(photref_group, db_session, merit_function)[source]
Return the diagnostics, ranking, and std for each photref_group image.
- Parameters:
photref_group – The group of images for which an independent reference needs to be selected: list of (_, image_id, channel) tuples.
db_session – Active SQLAlchemy session for DB queries.
merit_function (str) – Expression to evaluate for ranking images. May reference any diagnostic column as
qnt_<name>(rank) orstd_<name>(standard deviation).
- Returns:
pandas.DataFrame with one row per image/channel, columns for all available diagnostics by name, additionally the rank of the image in that diagnostic is added (qnt_<name>). Finally a ‘merit’ column contains the value of the specified merit function.
- autowisp.browser_interface.processing.select_photref_views.record_photref_selection(request, target_index, image_index)[source]
Record a single photometric reference frame selected by the user.
